title: Complex dislocation of the index metacarpophalangeal joint with entrapment of a sesamoid.
abstract: Entrapment of a sesamoid in a complex dislocation of the index metacarpophalangeal joint is a rare finding that may make even open reduction difficult. A case of unusual anatomic derangement of the volar plate is reported that highlights the underlying pathophysiology of complex dislocations.
